Merriam-Webster has announced over one hundred new words that will go into its 11th Edition Collegiate Dictionary. To determine which make the cut, they study the usage for sometimes decades before accepting them. Among the words are webinar, infinity pool, dwarf planet, Norovirus, and dirty bomb, but it is mondegreen that is our fave.

What is a mondegreen, you ask? According to M-W, it is a “noun defined as a word or phrase that results from a mishearing of something said or sung” first coined by author Sylvia Wright in the 50’s when she admitted that she misunderstood song lyrics. We know that some of our personal mondegreens include those from “Blinded By the Light” and “Louie, Louie.”

To celebrate, M-W Online is calling for submissions of your favorites through July 25. Already available online, the 2008 print update of the Eleventh Edition will be in bookstores September 1.
